build: Add -mno-sse for x86_64 build

It was reported that using -mno-sse2 alone can crash clang compiler when the code it compiles accesses floating-point or vector types. It seems adding -mno-sse fix the problem. I thought -mno-sse2 implies it but that doesn't seem like the case and caused a problem. Actually recent versions of clang have -mgeneral-regs-only option and we should prefer it. But let's keep the fix minimal for now. Signed-off-by: Namhyung Kim <[email protected]>
